When editing a segment's City field, use the incorporated name, or use the CDP (Census Designated Place) name when the place is locally known and/or more commonly recognized by that name. Segments outside of the official limits of incorporated or CDP areas should have the "None" box checked instead. Unincorporated areas (unless they are part of a Montana CDP) and greater urban areas outside of city/CDP limits should also be checked as "None".
Creating your own city overlays: You must have WME Geometries installed along with Qgis a free geographical information system. Follow t0cableguy's guide that he has put together. Cross reference your maps for accuracy with U.S. Census Bureau maps by selecting Place on the bottom right. In the drop down menu select Montana and the appropriate city or town. Also use MDOT's City and Urban maps.
Use of City Field
SEGMENTS:
For Freeways and Ramps, the "Primary City" name should always be marked "None". (There is no "Alternate City".)
For All Other Segments,
- The "Primary City" name should be an incorporated municipality or a CDP (Census Designated Place) if that segment is confirmed to be within the established geographic limits. If a segment does not lie within one of these, the "Primary City" should be marked "None". Instructions on how to select the appropriate city name are set forth in Determining Primary City Name.
- The "Alternate City" name is always the city named in the USPS mailing address. If the "Primary City" name is the same as the USPS city, an "Alternate City" name is not needed. Segments may have multiple "Alternate City" names which are valid and approved for use by the USPS.
- Duplicate City Names: You may find cities and/or CDPs with exactly the same name. If you believe you have encountered a city or CDP that is a duplicate of another in the same state, first confirm the findings with your State Manager(s) (SMs). Your SM will facilitate the necessary naming changes. The convention for dealing with duplicate city/CDP names is as follows:
- Two cities of the same name (append county to the city with the smallest population) (See two cities example in the table below)
- City and (at least one) CDP of the same name (append county to CDP(s) name) (See city with one or more CDP example) If there are multiple CDPs sharing a name with a city, all CDPs will have county name appended.
- CDP and (at least one) CDP of the same name (append county to the CDP with the smallest population) (See two or more CDPs example in the table below). The largest CDP is the only CDP that will not have the county appended to the name.
- When the county name is appended, use this format (County Co). As an example, Orange County would be appended exactly as "(Orange Co)"
| Type | Name | Population | County | In WME |
| (two cities) | ||||
| City | Happy | 25,000 | This | Happy (This Co) |
| City | Happy | 50,000 | That | Happy |
| (city with one (or more) CDP(s)) | ||||
| City | North Happy | 50,000 | That | |
| CDP | North Happy | 100,000 | Another | North Happy (Another Co) |
| (two (or more) CDPs) | ||||
| CDP | Glad | 15,000 | This | Happy (This Co) |
| CDP | Glad | 70,000 | That | Happy |
A "City" name is required.
- For PPs, APs, and PLAs, the "City" name, as well as the rest of the address, is determined by the business or entity. Whatever it identifies as the address should be used.
- For RPPs, use the USPS mailing address city for the "City" name.
